Paging Dr. Freud ...

For all the talk about the psychological implications of tonight's primary results, I feel like we need to have Sigmund Freud on the pundit desk tonight.

Clinton needed the win -- and the bigger, the better -- to help with the superdelegate argument and with fundraising. Candy Crowley is making the point right now that Clinton's camp is making the argument to superdelegates that Obama's failure to win any of the big blue states (with the exception of Illinois, his home state) indicates a potential fatal flaw in his candidacy: For all the new voters he's brought in, he isn't resonating with traditional, blue collar Democrats in blue states. And that means trouble for Democrats -- not only at the top of the ticket, but downticket, as well -- in the fall.

Thanks to the win tonight, and assuming a healthy enough win percentage to keep the dollars rolling in, we're going to be hearing a lot about that argument in the coming days.
